Return Value: This method returns a int value which is the HashCode value of the Writer instance.

Below methods illustrates the working of hashCode() method:

Program 1:




// Java program to demonstrate
// Writer hashCode() method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)
    {
  
        try {
  
            // Create a Writer instance
            Writer writer
                = new PrintWriter(System.out);

            String string = "GeeksForGeeks";
  
            // Write the string
            // to this writer using write() method
            writer.write(string);
  
            // Get the HashCode value using hashCode()
            System.out.println("HashCode value: "
                               + writer.hashCode());
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
Output:
HashCode value: 589431969

Program 2:




// Java program to demonstrate
// Writer hashCode() method
  
import java.io.*;
  
class GFG {
    public static void main(String[] args)

            String string = "GFG";
  
            // Write the string
            // to this writer using write() method
            writer.write(string);
  
            // Get the HashCode value using hashCode()
            System.out.println("HashCode value: "
                               + writer.hashCode());
        }
        catch (Exception e) {
            System.out.println(e);
        }
    }
}
